Abstract: A method and control unit for a start of an Otto engine operated at low temperatures, using ethanol and/or gasoline, having direct injection. The method includes generating by a high pressure pump a fuel pressure in a high pressure system connected to a high pressure reservoir; a sensor monitoring the fuel pressure in the reservoir and the system; injecting the fuel, by an injector, from the reservoir into a cylinder of the engine, the fuel pressure, an injection quantity and a fuel quantity being specified by a control unit based on, sensor the fuel pressure being specified based on the operating point of the engine up to an upper pressure which is below a starting pressure to which the fuel is increased before the fuel injection, and the fuel pressure in the reservoir and the system being limited to a maximum by an opening pressure of a limiting valve.
